Driving range display 'changes' after NTB11038 Svc Campaign

[DarkStar]

What if Nissan decreased the available portion of the battery?

As I stated earlier, I'm pretty sure they didn't do this since it would invalidate the EPA rating as required by law and be illegal under consumer protection laws regarding bait-and-switch. Nissan has stated publicly as well as in writing that the battery is 24 kWh customer usable. If we could no longer get in and out 24 kWh, that would be opening them up to some serious liability.

Are you in ECO mode or D and you must be driving at 70+ mph? Ya

Driving usual 65 on fwy plus a little stop n go, usually in eco mode although I have found that it doesn't make much difference on flowing fwy speeds. The thing that strikes me is I never averaged a miles per kw less than 3.6 but now I'm averaging 3.2-3.5. I'm puzzled.
I will know for sure after my Monday commute since I have a very good log for it. May just be coincidence, but I'm starting to get paranoid. I'll be glad when someone comes up with a add on battery pack so I will have plenty of range.

Sorry, I missed you said that. Yet, if all was changed was the range estimate, the bars should not be decreasing this fast, even if the rate of change for the last 2 red bars was adjusted. If those on this board that have access to the diagnostics software can verify that we still have 24 kwh available, it would be good info to have. The only other thing I can think of doing is running the car out of juice or low on juice to see if I can still drive the same number of miles as before.

Yes, if they did limit the usable battery without full disclose and consent by customers (I know I did not consent to such a change), they would have screwed up and some (me included) would not take that lightly.

Just chiming in my two cents, I have put about 40 miles on the car and am getting the "bars" that I expect from the car with no real change noticed. Now the range estimation is much different ( and I think better then before) but I haven't noticed my bars dropping any faster then before (could just be lack of attention on my part as most of my commuting is very short distances)

No problem. I'm suspecting that there is now more SOC % available after the bars are gone... Maybe each bar represents 7% SOC instead of 8% SOC each.

Code: Select all

Bars - Percent
12 - 100-93%
11 -  94-86%
10 -  86-79%
 9 -  79-72%
 8 -  72-65%
 7 -  65-58%
 6 -  58-51%
 5 -  51-44%
 4 -  44-37%
 3 -  37-30%
 2 -  30-23%
 1 -  23-16%
 0 -  16- 0%<-- The New Reserve

They've left the "Nissan Miles" calculator to still figure the range, but maybe now base it on a 100% to 16% SOC. This is the best theory I've been able to come up with, but I don't really have a good way to prove it...

Maybe someone else has the info!

That sounds possible, I hope you're right.

I'm going to run it completely out of juice sometime soon. That should get me the data I need; I'll see if I can drive the same number of miles given the same driving style and conditions.

*AND* keep track of how much is needed to charge it back to 100% (Kill-A-Watt, TED, 2nd meter, or other alternatives available to you).

I decided to take one for the team and see how low it will go, post update. The car is currently sitting half in my driveway, half in the street. I do NOT recommend trying to push this thing uphill (or even up a driveway) - it's HEAVY!

• I got the low battery warning at 8 miles and 1 bar SOC remaining.
• I got the very low battery (---) warning at 2 miles and 0 bars remaining after having traveled 8 miles on the trip meter.
• I got turtle mode after having traveled 13 miles on the trip meter.
• The car died on me after 14 miles on the trip meter.
• I coasted another tenth of a mile and had to push from there.
• Pushing on flat terrain was hard enough, the motor seemed to add significant drag. Trying to push it up my driveway was impossible. Maybe if I were Arnold Schwartzenneger...

This was all in D mode, 20-35mph speeds, climate control and headlights on.

CORRECTION: The first two miles after low battery were on the freeway at 65-70, and the next two miles were on a major surface street at 45-50. After that it was all neighborhood speeds.

Thank you for info, now all you need is a long extension cord to get inside garage

[GeekEV]

I've got one. It's sitting charging from my modded L1 charger as my wall mount won't reach. It's been 30 minutes so far and it still won't let me move it.
